Are Mint Plants Toxic to Dogs?

Some mint plants are toxic to dogs. 

Also known as mentha, mint is a genus of plants belonging to the family Lamiaceae. Grown in all types of environments, there are about 13 to 24 species that currently exist worldwide. Mint plants are known for their aromatic leaves, which are commonly used as culinary herbs in fresh or dried form. Aside from cooking purposes, the plant’s strong scent can help repel insects. 

Since dogs can eat certain types of mint, it follows that the entire plant of those varieties are non-toxic as well. Catmint, peppermint, spearmint, and wild mint are examples of canine-safe mint. On the other hand, garden mint, English pennyroyal, and perilla mint should not be grown if pets are around. 

What to do if your dog accidentally comes into contact with, chews, or eats mint plants: There’s nothing to worry about if your dog comes across a non-toxic mint plant. However, the problem lies in deciphering which is which, and possibly exposing your canine to a harmful one. 

When consumed in large amounts, garden mint has essential oils that can cause vomiting and diarrhea. Some dogs exposed to essential oils may even experience difficulty in breathing or lose consciousness. Eating a considerable portion of English pennyroyal can cause weakness, liver damage, and organ failure. 

Play it safe by contacting your veterinarian, and bringing a sample of the mint plant to the clinic for assessment. 

In summary: Since some mint plant species are toxic for dogs, it is best to get your vet’s approval before buying and growing one in your home. As a responsible dog owner, check out these plant lists created by ASPCA, PetMD, and Pet Poison Helpline. They’ll help you determine which ones are toxic and safe for dogs.
